Research evidence increasingly points to the large impact of sleep disturbances on public health. Many aspects of sleep are heritable and genes influencing traits such as timing, EEG characteristics, sleep duration, and response to sleep loss have been identified. Notably, large-scale genome-wide analyses have implicated numerous genes with small effects on sleep timing. Additionally, there has been considerable progress in the identification of genes influencing risk for some neurological sleep disorders. For restless legs syndrome, implicated variants are typically in genes associated with neuronal development...

BACKGROUND AND PURPOSE: There are several primary causes for excessive daytime sleepiness (EDS) and sleep disorders in patients with epilepsy. Up to now, studies in the literature report conflicting data in terms of both prevalence and aetiology. The aim of our study was therefore to evaluate the prevalence of EDS and some sleep disorders in a population of patients with epilepsy treated with no more than two antiepileptic drugs (AEDs). We also investigated the role of the depression of mood as a variable that can negatively affect EDS...

Restless legs syndrome (RLS) is a neuro-sensorimotor disorder affecting 2-4% of adults. It is characterized by intense urges to move the legs, associated with unpleasant sensory disturbances in the legs occurring at rest and manifests mostly in the evening and night, relieved by movement. Diagnosis is primarily based on clinical presentation and the consensus criteria for the diagnosis have been established. Antipsychotics, the dopamine antagonists, have been reported to induce RLS. Dopamine agonists, the effective first-line treatment of RLS, carry the risk of inducing or worsening psychosis...

We studied the impact of residual renal function (RRF) on clinical outcome and quality of life in 61 patients on peritoneal dialysis (PD). They were assigned to two groups, at the time of initiation of PD, based on their estimated glomerular filtration rate (eGFR). The high RRF group had eGFR ≥5 mL/min/1.73 m[2] and the low RRF group hade GFR <5 mL/min/1.73 m[2]. All patients were followed up at regular intervals for clinical and biochemical variables. Baselines characteristics including age, sex, body mass index and cause of the kidney disease were similar in both groups...

STUDY OBJECTIVES: Restless legs syndrome, also known as Willis-Ekbom disease (RLS/WED), is a frequent condition, though its pathophysiology is not completely understood. The diagnosis of RLS/WED relies on clinical criteria, and the only instrumental tool, the suggested immobilization test, may lead to equivocal results. Recently, neurophysiological parameters related to F-wave duration have been proposed as a diagnostic aid. The aim of this study is to assess and compare the diagnostic values of these parameters in diagnosis of RLS/WED...

In this paper, we first critically appraise the epidemiologic literature examining the association of restless legs syndrome (RLS) with cardiovascular disease (CVD) and then consider whether lessons learned from the study of cardiovascular consequences of other sleep disorders might inform a research agenda to examine the potential mechanisms of cardiovascular morbidity of RLS. Cross-sectional and longitudinal studies are both mixed as to whether there is a meaningful association of RLS and CVD. On the other hand, numerous cross-sectional and longitudinal observational studies have shown a strong association of obstructive sleep apnea (OSA) with CVD risk...

At the outset of genetic studies in restless legs syndrome (RLS), the disorder was assumed to be a classical monogenic disorder that runs in families. However, years of family studies did not reveal any causally-related genes or genetic variants. The advent of high-throughput genotyping technology led to a change; genome-wide association studies in large case-control samples became feasible, which led to the identification of first genetic risk variants for RLS. Variants detected by this approach are common ones, which that individually confer only a minor increase in risk of disease...

In this article, we review the original findings from MRI and autopsy studies that demonstrated brain iron status is insufficient in individuals with restless legs syndrome (RLS). The concept of deficient brain iron status is supported by proteomic studies from cerebrospinal fluid (CSF) and from the clinical findings where intervention with iron, either dietary or intravenous, can improve RLS symptoms. Therefore, we include a section on peripheral iron status and how peripheral status may influence both the RLS symptoms and treatment strategy...

Sleep disorders in humans are increasingly appreciated to be not only widespread but also detrimental to multiple facets of physical and mental health. Recent work has begun to shed light on the mechanistic basis of sleep disorders like insomnia, restless legs syndrome, narcolepsy, and a host of others, but a more detailed genetic and molecular understanding of how sleep goes awry is lacking. Over the past 15 years, studies in Drosophila have yielded new insights into basic questions regarding sleep function and regulation...

BACKGROUND AND AIM: There has been increased interest in sleep disorders in patients with inflammatory bowel disease (IBD). Studies in North America and Europe reported that the prevalence of restless legs syndrome (RLS) is much higher in patients with Crohn's disease (CD) than in the general population. The aim of this study was to reveal the prevalence and clinical features of RLS in Japanese patients with IBD and investigate the influence of RLS on sleep quality and quality of life (QOL)...

There have been few quality of life studies in patients with idiopathic rapid eye movement sleep behaviour disorder. We compared the quality of life in idiopathic rapid eye movement sleep behaviour disorder patients to healthy controls, patients with hypertension, type 2 diabetes mellitus without complication and idiopathic restless legs syndrome. Sixty patients with idiopathic rapid eye movement sleep behaviour disorder (24 female; mean age: 61.43 ± 8.99) were enrolled retrospectively. The diagnosis was established based on sleep history, overnight polysomnography, neurological examination and Mini-Mental State Examination to exclude secondary rapid eye movement sleep behavior disorder...

BACKGROUND AND AIMS: Restless legs syndrome (RLS) is a movement disorder associated with adverse health outcomes and decreased quality of life. Small case series suggest that symptoms of RLS occur during opioid withdrawal. However, the prevalence is unknown. METHODS: We conducted an observational study to determine the prevalence of RLS among inpatients patients receiving buprenorphine detoxification from opioids. To assess the specificity of RLS to opioid detoxification, we also evaluated patients receiving detoxification from alcohol as a comparison group...

BACKGROUND: Sleep disorders and depression are prevalent conditions in patients with end-stage kidney disease. These co-morbidities have significant overlap and compounded morbidity and mortality burden. This overlap presents challenges to optimal clinical assessment and treatment. The goal of this study was to assess the prevalence of sleep disturbance in patients on maintenance haemodialysis, and to assess the impact of depressive affect. OBJECTIVES: This was a single-site, single group, cross-sectional study of 69 English-speaking patients undergoing maintenance haemodialysis...

Opioid receptor agonists are known to relieve restless legs syndrome (RLS) symptoms, including both sensory and motor events, as well as improving sleep. The mechanisms of action of opioids in RLS are still a matter of speculation. The mechanisms by which endogenous opioids contribute to the pathophysiology of this polygenetic disorder, in which there are a number of variants, including developmental factors, remains unknown. A summary of the cellular mode of action of morphine and its (partial) antagonist naloxone via α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptors and the involvement of dendritic spine activation is described...

Acute hyperkinesia after discontinuation of tramadol in a patient with chronic pain using citalopram and pramipexole for restless legs syndrome (RLS) has not been reported. An 81-year-old female was admitted for increasing hyperkinesias of the whole body after she had discontinued tramadol 300 mg (taken during 3 months) without tapering 4 days earlier. In addition, she was on treatment with pramipexole (0.18 mg) for RLS for years, citalopram 10 mg/day for ~4 years, and fentanyl 75 μg/day for 1 year. Hyperkinesias did not respond to benzodiazepines, quetiapine, biperiden, or valproic acid...

STUDY OBJECTIVES: The association between restless legs syndrome (RLS) and Parkinson's Disease (PD) has been extensively studied with inconclusive results, therefore we prospectively examined the associations of the presence of RLS with development of incident PD. METHODS: From a nationally representative prospective cohort of almost 3.5 million US veterans (age: 60±14 years, 93% male, median follow-up time of 7.8 years (IQR: 6.4-8.4 years)), we created a propensity-matched cohort of 100,882 PD-free patients and examined the association between prevalent RLS and incident PD...
